COILING MECHANISM OF CARDlNG-ENGINES AND DRAWING-FRAMES.

SPECIFICATION forming part of Letters Patent No. 224,979, dated February24, 1880. Application filed October 2, 1879.

To all whom it may concern Be it known that I, JAMES WOLSTENOROFT, ofPhiladelphia, Pennsylvania, have invented new and useful Improvements inthe Coiling Mechanism of Oarding-Engines and Drawing- Frames, of whichthe following is a specification.

My invention relates to an improvement in that class of coilingmechanism for cardingengines in which delivery-rollers are combined witha revolving plate having an inclined throat, through which the sliverdelivered by the rollers is directed to the can below the said plate;and myv improvement consists of the combination of the coiler withdeliveryrollers clothed, or partly clothed, with paper or itsequivalent, as described hereinafter, so as to prevent the interruptionof the progress of the sliver through the throat of the coiler, whichfrequently takes place when the slivers are of dyed cotton.

In the accompanying drawings, Figure l is a vertical section ofsufficient of a drawingframe to illustrate my invention; Fig. 2, a sideview of Fig. 1; Fig. 3, a perspective diagram without the frame; andFig. 4, the same,

illustrating the defect which my invention is designed to remedy.

A and A are the two delivery-rolls of a drawing-frame, the roller Abeing slightly above the roller A, and its journals being,

adapted tOiHCllIld SlOtS (shown by dotted lines, Fig. 1) in the frame B,so that the sliver as shall be pressed by the roller A against theroller A. This is an arrangement common to drawing-frames of the usualconstruction, as well as to carding-engines.

The frame 13, which forms a part of the general frame-work of themachine, supports the coiler D, which is adapted to an annular recess inthe said frame, and which has teeth on its periphery, so as to be drivenby a pinion on a vertical shaft, as shown by dotted lines in Fig. 1. Thecoiler has an inclined opening, c,'through which the sliver passes frombetween the rollers to the can G, placed beneath the coiler. Astationary cover, H, supported by the frame B, iucloses the coiler, thiscover, which has a central opening for in connection withdrawing-frames.

The rollers are driven, as usual, at appropriate speed, in thedirectionof the arrows, and.

the sliver is drawn downward by the two roll ers, and delivered therebythrough the opening in the cover and through the inclined opening in thecoiler, by which the sliver is coiled as it is deposited in thecan G.

Sliver delivery and coiling mechanism differin g somewhat inconstruction from that described above is used in connection withcarding-engines and drawing-frames; but as my invention is confined tothe delivery-rollers it will be unnecessary to refer to anymodifications of the' coiling device.

When undyed cotton is operated on by the drawing-frame the slivers passfreely through the cover and coiler without interruption; but when dyedcotton is used the passage of the rupted, the opening in the coilerbeing choked and the slivers accumulating in a mass between the rollersand the cover, as shown in Fig. 4, and this involves the necessity ofstopping the machine in order to clear away the obstructing slivers.

Occasionally the breaking of the teeth of the coiler or of the pinionwhich drives it results from the accumulation of the slivers at the 1point indicated.

These accidents, which occur most frequently when the atmosphere is dry,I attribute to the presence of electricity; but, whatever may be theimmediate cause of this interruption of the progress of the slivers, Ihave found that the difficulty may be entirely obviated by clothing therollers, or those portions with which the slivers come in contact, withpaper m, as best observed in Fig. 2. The paper should be smooth, hard,and thin. Fine, well-calendered Manila paper, for instance, will servethe purpose.

I generally use ordinary shellac varnish in applying the paper to therolls. A strip of thin glazed muslin carefully wrapped round the rollerswill serve the same purpose, and is more durable than paper.Tracing-cloth may also be used as a covering for the rollers;

but whatever clothing is employed it must be hard and unyielding.

. I claim as my invention The combination of the coiler of adrawingframe or carding-engine with delivery-rollers clothed, or partlyclothed, with paper or its :0 equivalent, as set forth. In testimonywhereof I have signed my name to this specification in the presence oftwo subscribing witnesses.
